COMBINATIOIi SASH-LOCK- AND AIZARM.

TWIN whomit may concern: v 7

.Be it known that 1, JOHN Tnsooxmo, a. citizen of the United States, residing at New llaveu, inthe county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Combination Sash-Locks and Alarms, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved immbination sash lock and alarm and has for ils'oliject to'provide a device which may be. easily and quickly applied dow frame and the sashes. and \jvhiclifwill jadmit of said sashes llC ll lgOPCliQd ma limited exteut,'said locking means being ineluded in an electric circuit, the circuit-be ing closedtosouml the alarm upon an attempt to more i u-rcss to the apartment, z 7 Another and more specific object of the invention is to provide a iiiovablearm or barrier disposed above the]top ;lnu1;of the lower sash, and restiugat oue end-against the upper ,sasl i, anda stop Jnember carried by the upper sash with whichsaid barrier is adapted to be engaged when the lower sash is raised, and eircuitwires connected dosald stop member and the barrier to close an electric circuit and sound the. alarm. I

Still another object of the invention isto' produce a device of the above charactersimple l1 l itsfconstruc which is extremely tion. may be. produced at. small cost and is hi hly etficientand positive inoperation. V

With the above and other objects in view Y "as will become apparent as the description proceeds. the invention ,eonsists. in certain constructions,

fully describe and'claim. For aijull understanding of'tliel nvention, "l'eferenec is to 'be had to the following descriptionfand aecompanyingjdrawings, in "\vlii(3l1.;'

Fig. 2 is-f'a section *talu-n on the" line 2-2 of Fig, 1; Fig. 3 is a view similar'to Fig. .2; slightl v' modified .form of the device; an "Fig, 4 is a fragmentaryplan view of the "lower sash' an'd the stop member or barrier illustrated in Fig.

ignates a window frame or casing and 6 indicates the molding or guide strip for the lower window sash which is designated by The usual parting bead 6' is formed on the sides of the frame 5 and separates the lower sash 7 from the upper sash 8.

A movable arm or barrier 9 has one of its endspivotally mounted upon the shank of a screw 10 which is threaded in the mold- 'of the frame 5. This barrier arm is adapted when in its operative posi tiull tti extend transversely across the top barjof the lower sash 7,

as clearly shown in ,FigQjQ, the free end, .offsziid9bar resting against the upper sash,said barbeing (11sosedat ;al l;' inclination asshown so as to fleetually prevent loweringof the upper This .'free end of peiyedgeivith a flattened face ll which is adapted to abut. squarely against the lower einl of stop plate 12. Thissto plate is secured to one of the stiles of tie u per sash S by means of the screw 13, said p ate,

however, being capable of swinging movemen'tlnpon the'screw to the position shown F 1g .1, so that the sashes may, be raised or lowered relative to each other. Tl|e barrier arm 9 and the stop plate 12 are each prtivid'ed with anorifice to receive metallic plugs or tips upon the ends of the circuit wires 1' and 15, respectively,

said wires extending fromthe opposite poles of an electricbattery indicated at 16. In

the battery circuit, a bell or other alarm de- ,vice indicated at \17 is arranged.

In the operation of the device as above described, the barrier arm'is normally disosed upwardlyatian angle from its'jpivoted end and rests at its free end against the bar is solocated that the lower sash may be elevated to a point just beneath said bar in order to ventilate the apartment, in which position the lower sash is shown in Fig. 2. Upon the..at-tempt to elevate the lower sash beyond this point so as to gain access to the apartment, the top ba r of said sashcontacts with the lower edge of the barrier arm 9 and forces the free end thereof upwardly into engagement with the lower end of the plate 12 on the upper window sash, thus closing the electric circuit and ringing the alarm bell. When the barrier arm is in its normal position and engaged with the upper sash, any downward movement of saidsash is rendered impossible, while any attempt to raise the lower sash above its adjusted-position will move ment of thearm 9' and .theplate 12, the electric circuit is normally open. A strip of insulating material indicated at 18 is. $61. cured to the top bar of the lower sash upon. which the barrier arm 9 engages. Suitable insulation is also provided betweenthis arm and the window frame andbetween the stop plate 12 and the stile ofthfsash 8.

By' mj'eans' ,of this arrange f ment, the uppersashrnay either-be lowered until the end of-"the jplutej 12'." is' disposed closely adjacent to the 'plate' 19; or'saidsash lowered aless extent and the lovlrerfsash' 7 raised. Thus the movement of sashes may be obtained, the extent-pos um; move ment being approximately equivalentfto' one half of the space betive en-ttheplates 12'; and

It-is under plate" 19 is" stood that this additional sto to be used in connection wi the barrier arm 9 so that ventilatioi'i' nay be obtained at either the top or, bottom of the window or at both the top and bottom.. When the arm 9 is used, 'theplate 19 is swungto its.

inoperative sitio'n-show'nin dotted lines in Fig. 4 and order'to dispose thearm 9 in its inoper ative position shown in'dotted lines, the plate 12 is first swung to'the dotted line position shown in Fig. 1 so that said arm may be lifted and swung to the dotted line position shown in Fig. 1 so that said arm may be lifted and swung inwardly out of the path of movement of the lower sash. Both sashes can then be adjusted to any extent desired. T

From the foregoing, it is believed that the t a rm u eth'efefiempt't dow: to sue asement-yes wouldperrn t of aid arm swung across the topbar of the lower sash as shown in Fig. 2. In
